Hardware Setup  
CPU (Central Processing Unit)  
The mainboard supports Intel® Core 2 Duo/ Core Duo/ Core Solo/ Celeron M/  
Celeron LV 423 BGA (with BGA Passive Cooler) processors in Socket M. When you  
are installing the CPU, make sure the CPU has a heat sink and a cooling fan  
attached on the top to prevent overheating. If you do not have the heat sink and  
cooling fan, contact your dealer to purchase and install them before turning on the  
computer.  
Important  
1. Overheating will seriously damage the CPU and system. Always make  
sure the cooling fan can work properly to protect the CPU from overheating.  
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)  
between the CPU and the heatsink to enhance heat dissipation.  
3. While replacing the CPU, always turn off the power supply or unplug the  
power supplys power cord from the grounded outlet first to ensure the  
safety of CPU.

CPU & Cooler Set Installation  
1. Place the CPU on top of the socket. Make sure to align the gold arrow on the CPU  
with the arrow key on the socket.  
2. Push the CPU down until its pins securely fit into the socket.  
3. On the front end of the CPU socket is a  
locking mechanism designed into the  
form of a screw. Make sure that you  
actuate or deactuate this mechanism  
with a screwdriver before and after in-  
stalling the CPU.  
4. Release the metal clips on the retention  
mechanism.  
Mainboard photos shown in this sec-  
tion are for demonstration only and may  
differ from the actual look of your  
mainboard.

Troubleshooting Action  
Reseat the memory, or replace with known good modules.  
Fatal error indicating a serious problem with the system. Consult your system  
manufacturer. Before declaring the motherboard beyond all hope, eliminate the  
possibility of interference by a malfunctioning add-in card. Remove all expansion  
cards except the video adapter.  
4-7, 9-11  
If beep codes are generated when all other expansion cards are absent, consult  
your system manufacturers technical support.  
If beep codes are not generated when all other expansion cards are absent, one  
of the add-in cards is causing the malfunction. Insert the cards back into the  
system one at a time until the problem happens again. This will reveal the  
malfunctioning card.
